ToendaCMS is prone to an HTML-injection scripting vulnerability because the application fails to properly sanitize user-supplied input.

Attacker-supplied HTML and script code would execute in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user; other attacks are also possible.

This issue affects ToendaCMS 1.5.3; other versions may also be affected.
